"When you have exactly the same material for the tweeter and midrange the speaker sounds 100% coherent, there is no issue in getting the drivers to blend."
I’m not a speaker designer nor an engineer by any stretch, but there’d seem to still be several issues left to deal with, in addition to driver material, that would determine how coherent individual drivers and/or a speaker sounds. You’re also talking pretty tough about outperforming some pretty good speaker manufacturers. Sound like interesting speakers though.
